The world today is powered by electricity, and without it, we would probably be back in the stone age. Just like any other field, the field of electrical engineering is revolutionising and changing the way we consume power for our day-to-day necessities. Recently, they have contributed to enormous strides in energy efficiency, accessibility, mobile technology, telecommunications, transportation, and much more. Let us look at some of the latest ideas in the field.
The speed limit for Wi-Fi broken a few years ago in Germany by delivering 40 GBs of data per second over a distance of approximately a kilometre. The main innovation behind this success was a new set of chips capable of processing signals at frequencies that are higher than usual. Theoretically, the shorter the wavelength, the stronger the Wi-Fi can be.
Wireless Wearable Tech
What then was just an idea in computing science, has now become a reality – Personal Area Network. We can now operate devices on a smaller scale and in a broad environment with a seamless interface. These wearable devices are engineered to be used in some scenarios in place of mobile phones such as to authenticate access to machinery and vehicles, and so on.
Of course, this is something you must’ve heard off as it is already in the market on a considerably large scale. The virtual reality devices are made to help individuals experience ‘real life’ while seeing things virtually. Although this innovation draws in various disciplines, electrical engineering is its key aspect. The earliest VR sets included a pair of gloves along with a headset, making the user more stationary. With the advancement in this technology, positional tracking is said to make VR more interactive.
Smart Electrical Grids
With natural resources running out and energy systems becoming more complex, bringing in the electrical department seems only viable and a great alternative. With these systems becoming diverse, smart grids are gaining importance worldwide. These grids involve the usage of various technologies at each step to detect malfunctions, improve flow control, and automate service delivery. With end-to-end communications among power plants, distribution sites, and the end user’s electrical point-of-presence, it becomes possible to increase efficiency and reduce costs simultaneously.
Green Energy Electrical Power Converter
While collecting energy is one task, converting it into electricity and supplying it to the end user is another. A new power converter has been invented to make it easier for users who incorporated renewable energy to shunt the excess energy into the power grid. This innovation has the capacity to make the rooftop solar power systems easier and also, encourage homeowners to use energy efficient technology.
High-Efficiency Photovoltaic Cells
One of the permanent challenges of modern electrical engineering is to find an implementation of photovoltaic technology that is, at the same time, efficient, effective under varying operating conditions, and highly resistant to damage, all while not being cost-prohibitive. Various engineering approaches have been used to increase collection and distribution efficiency, though perovskite-based cells have recently gained the most attention at major research facilities.
Eye Tracking Technology
Eye tracking has become essential, not only to deliver messages but to help the disabled gain access to things through their eye movement. The basis of this technology becoming a reality are sensitive electronic sensors. Further, this technology could also play an important role in commercial businesses to better understand the best interests of their consumers.
Electrical engineering is a field of great potential given the present situation, and a person who pursues their career in this field from Ashoka Institute of Engineering and Technology has umpteen opportunities to be a part of how the future of power is going to be shaped.
